Why you might want to have a Plan B (inside) Sunday
Forecast precipitation from the WRF/NAM model for the 6 hour period valid 12z (7 am) Sunday morning. The bulk of the rain passes just to the south and east of St. Cloud. The model prints out a whopping .01" of rain for STC, but over .25" for the Twin Cities. Here is another classic example where the Twin Cities metro forecast has absolutely no relevance to residents of St. Cloud and the rest of central Minnesota. That difference of 70 miles or so can be HUGE on a day like Sunday. Although gray, most of Sunday will probably be dry for the greater St. Cloud area, a few spits of rain/sprinkles, while the Twin Cities metro may see 3-5 hours of rain, enough for puddles, probably enough to spoil many outdoor events. Have a Plan B ready, just in case.
